Gets a custom material suitable for use withUPointSetComponentfor round points. Note that this material uses translucent blend mode, and therefore can't always follow the correct draw order relative to other translucent objects (and within the point set). If this is not acceptible, you will need to use the depth tested square point material (GetDefaultPointComponentMaterial with bDepthTested = true).
